Partial A-V Canal with Subaortic Stenosis
Abstract
A case report of partial atrioventricular canal with subaortic stenosis in a 3 years old boy emphasized the importance of surgical approach for left ventricular outflow tract through the interventricular septum. Not only for reasons of gaining good exposure of all important structures in the left ventricular cavity, this approach also facilitated effective removal of all fibrous tissue and abnormal muscular tissue from the left ventricular outflow tract.
In addition, the left ventricular outflow tract which may be hypoplastic can be simultaneously enlarged pericardial patch with this approach. The conventional approach through a small aortic incision for the release of outflow tract obstruction may be dangerous in this situation.
